Space Forever Stamps

Space Forever stamps feature astronomy, exploration, planets, spacecraft, or related science themes. They are a natural fit for science correspondence, classrooms, invitations, clubs, and recipients who enjoy space, while the specific product page identifies the actual USPS issue offered.

Choose by subject and issue

Space-themed releases can focus on very different subjects. Compare the artwork, issue title, year, and format instead of treating every space design as interchangeable. If visual consistency matters for a batch mailing, check that the selected quantity comes from the same listed issue.

Use on qualifying mail

When a product is an ordinary Forever stamp, it carries the current First-Class Mail one-ounce letter rate value. Heavy, rigid, square, thick, or international mail can require additional postage or another service. Review how Forever stamps work for the value rule.

Before buying

• Confirm the exact design shown.
• Check sheet, booklet, or roll format.
• Verify the selected stamp count on the product page.
